Just to be clear of what exactly I propose I drafted a patch. PFA.
I've tested it with PG13 and
CREATE AGGREGATE public.array_accum(anyelement) (
SFUNC = array_append,
STYPE = anyarray,
INITCOND = '{}',
PARALLEL = safe
);
CREATE OPERATOR ##% (leftarg=anyarray,
rightarg=anyelement,function=array_append);
Operator output currently look a bit strage, but does it's job.
pg_upgrade_output.d/operators.txt:
In database: postgres
(oid=16385) ##% in public
Thanks!
Best regards, Andrey Borodin.
